5 Commissioning and measuring mode
Before switching on the IVMI for the first time, please follow the instructions in the
following section.
5.1 Commissioning
Check that

the IVMI has been installed correctly and that all screw connections are
sealed.

the electrical wiring has been connected properly.

the measuring system is vented by flushing.
5.2 Switching on and off
The IVMI has no switch and can therefore not be switched on and off independently.
Switch-ing on and off takes place via the connected supply voltage.

Switch on the supply voltage.
The green LED lights up once for~1 s. The IVMI is ready
and goes into measuring mode.
5.3 Measuring mode
In measuring mode, the green LED flashes proportional to the measured flow.
The human eye cannot detect the flashing any longer from a fre-
quency of ~30 ... 40 Hz.
In that case the green LED seems to be lit permanently.
The following subsections only apply to devices which have the correspondent functionality.
IVMI with frequency output
The IVMI provides according to the version a flow
pro-portional NPN, PNP or Push-Pull square wave
signal.
The frequency of the pulse output changes
according to the flow (
